Question

A certain freezing process requires that room temperature be lowered from 40°C at the rate of 5°C every hour, What will be the room temperature 10 hours after the process begins?​

Answer 1

Answer:

The present room temperature = 40\degree C40°C

The room temperature decreasing every hour by rate of = 5\degree C5°C

The room temperature after 10 hours will be

= 40\degree C\ +\ 10\times\left(-5\degree C\right)40°C + 10×(−5°C)

= 40\degree C-50\degree C\40°C−50°C

= -10\degree C−10°C

so, the room temperature after 10 hour = -10\degree C−10°C

Answer 2

Answer:

the rooms temperature before the freezing process = 40°C

temperature to be lowered every hour = 5°C

duration of process = 10 hours

temperature reduced in the 10 hours process = 5 X 10 = 50

temperature at the end of 10 hours = 40° - 50°

= (-10°)

ANSWER = -10°
